Conformable wound dressing

Abstract

A wound dressing comprising an absorbent pad, an adhesive layer, and a backing layer is described, along with a dressing support layer configured to retain and deliver the wound dressing to a wound, the dressing support layer having a radial configuration that forms a plurality of alternating covered and uncovered portions of the backing layer along the perimeter of the wound dressing.

Description

FIELD OF THE INVENTIONThe invention relates to wound dressings, and more particularly to a thin film composite dressing and a radial support delivery system.BACKGROUND OF THE INVENTIONWound dressings using an absorbent central area surrounded by a larger adhesive film are known. For example, U.S. Pat. No. 5,738,642 (the '642 patent) shows a wound dressing and delivery system comprising a thick absorbent pad placed in the center of a thin backing. A carrier frame surrounds the perimeter of the wound dressing, providing sufficient support (e.g. rigidity) to the backing to facilitate handling of the dressing during application to a wound. The dressing taught in the '642 patent is useful for application to a large variety of wounds. However, a need remains for a wound dressing that can be more effectively applied to irregular surfaces, such as a heel or shoulder. Currently, wound dressings are sometimes cut toward their center to make a cone shaped dressing, but these dressings have sig...

AI Technical Summary

Benefits of technology

The present invention provides a thin, flexible wound dressing with a delivery system that makes it easy to handle and apply to irregular surfaces, such as a heel. The dressing has an adhesive layer and a support layer that retains and delivers the dressing to the wound. The support layer has a radial configuration that allows for easy application on non-planer surfaces. The technical effects of this invention are improved adhesion to irregular surfaces and easy application of an absorbent pad to the heel of a foot while maintaining a sterile perimeter around the wound.

Problems solved by technology

Currently, wound dressings are sometimes cut toward their center to make a cone shaped dressing, but these dressings have significant limitations, including the risk of infection along the line of the cut line, difficulty in applying with one hand, and leakage of fluids from the wound along the cut line.
